IB Physics
An IB Physics program at HL and SL levels that explains physical phenomena through mathematical models and develops experimental design skills.
Curriculum / Syllabus
- Space, Time and Motion
- The Particulate Nature of Matter
- Wave Behaviour
- Fields
- Nuclear and Quantum Physics
- Internal Assessment (IA) Guidance
Exam & Course Strategy
Paper 1 is multiple-choice, Paper 2 involves open-ended data analysis and problem-solving, and Paper 3 for HL students focuses on additional higher-level topics.

Lesson-by-Lesson Curriculum Plan
IB Physics (SL & HL): 25-Lesson Curriculum Plan
This program follows the five themes of the IB Physics guide with first assessment in 2025: A (Space, time and motion), B (The particulate nature of matter), C (Wave behaviour), D (Fields), and E (Nuclear and quantum physics). Lessons marked HL only cover the additional higher level topics.
Each theme ends with practice on exam-style questions for Paper 1 (multiple-choice and data-based questions) and Paper 2 (short-answer and extended-response questions).
Flow of a standard 90-minute lesson
- 0–10 minutes Warm-up, quick review of the previous lesson, or a mini-quiz.
- 10–55 minutes Lecture, analysis, and theoretical review of the new topic.
- 55–85 minutes Guided problem solving: the student works exam-style questions under my direct supervision and receives instant feedback.
- 85–90 minutes Summary, homework, and wrap-up.
